Last week we built a head tracking device, from a project originally created by a professor at Carnegie Mellon University named Johnny Lee.
His other project, the Wiimote powered interactive whiteboard, is just as impressive and twice as useful. It turns any projector, monitor, or laptop screen into an interactive display.
Here is an eye-popping video by Dr. Lee giving an example of his interactive whiteboard technology:
After you build the infrared LED pen (detailed later in this post), you can use it just like you would your mouse. Move around windows, draw diagrams, and distract annoying kids by opening Microsoft paint and letting them have at it. It is not only a simple software toy, but it can be immensely useful as a presentation tool.
